..To use the 4D data acquired under different conditions or using different modalities, an algorithm for registering 4D images must be in place. We developed an automated 4D-4D registration method to take advantage of 4D information...

..Noise in the reconstructed CBCT image acquired with a low mAs protocol was greatly suppressed after the proposed sinogram domain image processing, without noticeable sacrifice of the spatial resolution...

Gaining confidence in biological interpretation of the microarray data: the functional consistence of the significant GO categories

..We demonstrate that the average detection rate of the improved morphological filter is much higher than that of the other two methods, and there is no false detection for normal EEG signals with the proposed method...

..The sensitivity of array results to normalization is an open question. No clear standard for comparing or judging normalization methods has yet emerged, and the effects of normalization on gene-to-gene co-expression are unclear...

ReAS: Recovery of ancestral sequences for transposable elements from the unassembled reads of a whole genome shotgun

..Tested on the japonica rice genome, ReAS was able to reconstruct all of the high copy sequences in the Repbase repository of known TEs, and increase the effectiveness of RepeatMasker in identifying TEs from genome sequences...

..It is a sensible approach for matching probes across platforms. We conclude that UniGene alone is insufficient to match genes across platforms. Refined matching based on RefSeq significantly improves the quality of matches...

Extract echo signal in HFR imaging system

..With the new method we have developed, many other imaging methods, such as Doppler blood flow and elastic imaging, can be easily combined with HFR method to give more information of the imaged objects...

..Our results indicate that depth-weighted optical signals may infer cardiac activation dynamics, such as the mode and the direction of the propagation, the spatial distribution of depolarization or repolarization...

..In applications with publicly available data sets, our test results are similar to the conventional approach which assumes independence. We argue that the independence assumption is not detrimental...

..We conclude that adenosine activates the 50 pS K channel in the basolateral membrane of the TAL and the stimulatory effect is mainly mediated by a PKA-dependent pathway via the A2 adenosine receptor in the TAL...
